A Highland Park High School senior and baseball player is facing sexual assault charges after an acquaintance accused him of raping her after a concert Saturday.

Ryan Romo, 18, was arrested by University Park police Monday after investigators recorded two conversations between Romo and the girl about the incident, which occurred in the back of Romo’s Chevy Tahoe, according to an arrest warrant affidavit.

In the first conversation, Romo offered to get her the morning-after pill, which can prevent pregnancy, and he suggested they “hang out” together again, the affidavit says.

In the second conversation cited in the affidavit, she said, “I just wish it didn’t happen like that, you know like.” He replied, “Yeah.” She continued, “Like I wish, cause, I said stop … I said no. … I wish you’d stopped you know or not done it.” Romo then replied, “OK, you’re making me feel bad, wow.”

Romo was charged with sexual assault of a child, a second-degree felony. Police declined to release the girl’s age.

Romo’s attorney, Reed Prospere, declined to comment.

According to the arrest warrant affidavit, the girl told police that she ran into Romo at a concert at the Palladium Ballroom on Saturday night and took a cab with him to his Chevy Tahoe. She told police they drove to his house and parked on the street.

She said they began to kiss and make out in the back seat. She said that when he tried to have intercourse, she told him, “No, I don’t wanna do this,” and screamed “stop” because she was in pain, but Romo did not listen.

After Romo dropped her off at home, the girl’s mother noticed that she was upset and asked her what had happened. Her mother took her to Baylor Medical Center at Plano for a rape exam that showed the girl had a tear and abrasions, according to the affidavit.

A gynecologist did a follow-up exam the next day and told police the laceration and abrasions appeared to have been caused by force, according to the affidavit.

On Sunday night, University Park police recorded a phone call between the girl and Romo. In the phone call, Romo acknowledged that he had sex with her and told her, “I had fun. We should definitely hang out again,” according to the affidavit.

The next day, the police recorded the second conversation while the two were sitting in the girl’s car.

Romo was released from the Dallas County Jail on Tuesday on $100,000 bond. He was ordered to have no contact with the girl or her family or go any place that they frequent, according to court records.

Romo plays for the Highland Park High School baseball team and led the team in RBIs last season.

A call to his father, Adam Romo Jr., chief executive officer of Eatzi’s Market & Bakery, was not returned Wednesday.

Highland Park ISD spokeswoman Helen Williams said in a statement that the district does not discuss student discipline matters and cited federal privacy laws.

“When a situation involving an HPISD student is serious enough to necessitate the involvement of police officials, we cooperate fully,” the statement says. “At the same time, we remain committed to respecting the ethical and legal guidelines and laws that protect our students’ right to privacy.”
